This story came back to me.
Two monks arrive at a river to find a woman waiting at the brink wondering how she's going to get over. One of them hoists her on his shoulders and carries her across.
A hour later- several miles down the road- the other monk turns to him and says, "I can't believe, you just did that. What about your vows? You're not supposed to have anything to do with women."
And the other says. "Oh, that woman. I'd forgotten. I left her behind on the bank, but I see you're still carrying her."
